It is desired to chill 3m³ of water per hour by means of horizontal coils in which ammonia is evaporated. The steel coils are 2.13cm outside diameter and 1.71cm inside diameter and the water is pumped across the outside of these at a velocity of 0.8 ms'. Estimate the length of pipe coil needed, if the mean temperature difference between the refrigerant and the water is 8°C, the mean temperature of the water is 4°C and the temperature of the water is decreased by 15°C in the chiller. (53.1m) It is desired to chill 3m³ of water per hour by means of horizontal coils in which ammonia is evaporated.
